There are many people out there (me being one of them) who can vouch that animals have feelings; they feel compassion and love, as well as pain!

It's up to us to save the world for tomorrow: it's up to you and me.

Chimps are very quick to have a sudden fight or aggressive episode, but they're equally as good at reconciliation.

I always loved animals. And when I was ten, I decided I had to go to Africa and live with animals and write books about them.

I do not want to discuss evolution in such depth, however, only touch on it from my own perspective: from the moment when I stood on the Serengeti plains holding the fossilized bones of ancient creatures in my hands to the moment when, staring into the eyes of a chimpanzee, I saw a thinking, reasoning personality looking back. You may not believe in evolution, and that is all right. How we humans came to be the way we are is far less important than how we should act now to get out of the mess we have made for ourselves.

To me, cruelty is the worst of human sins. Once we accept that a living creature has feelings and suffers pain, then by knowingly and deliberately inflicting suffering on that creature, we are guilty, whether it be human or animal.

I just have this absolute belief that humans are moving away from cruelty and destruction towards a time when we can truly live in harmony with nature. When we understand that there is a spiritual power around us from which we can draw strength. That is where I believe human destiny ultimately is taking us. I just hope we have time.
